SECTIONAL RADIATOR FOR MOTOR VEHICLES. i

application mea March 16, 1925. v'serial No. 15,132.F A

Thisinvention relates mainly to internal combustion engine radiators,and more especially to large capacity sectional radiators adapted forportable power plant units and having top and' bottom tanks withinter--`- changeable radiating means interposed.

The main objects of the invention are to provide a simplified and moredurable form of radiator construction adapted for ready l0 manufactureand interchangeability of parts for renewals and repairs; to provideanimproved form of construction for the top and bottom end connectionsof the radiator part, meansor sections; to minimize-the v5 amount ofcoring necessary Ifor molding the parts; to provide a better form of'indivvidual sectidn headers, adapted for exterior application of thefasteners; to provide an improved form of top and bottom tanks; toprovide such headers and 'tank connections therefor adaptedtoaccommodate and .assure 'equalization of water distribution throughoutall of the passageways in each.

section; and to provide for loose fitting fasi teners which may bereadily set tightly in clamping relation to hold the sections de--mountablyg andto so construct the section headers'and seats therefor onthe tanks Athat tight @connections may bev attained by a il@ singlemanually releasable fastener at each 'oint. ,y Y] An illustrativeembodiment of this invention is shown by the accompanying drawings, inwhich- Fig. l is mainly a front elevation of the upper part of aradiator withthe right hand unit in vertical cross section, as' at thelinethe bottom part of the radiator, on `the line Fig. 4 isa fragmentaryfreut View of the lower right hand cornei` of the radiator rep-vresented in Fig. 1, with the right hand unit shown in vertical crosssection, correspond'k ing. with the upper end thereof as viewed -in Fig..1. 1

formed into shape from sheet metal.

Fig. .5 shows that position of the header which it assumes whendisposedat'the top 4Fig. 6 is an enlarged detail of Fig. 2 and showsespecially one ofthe `water passageways and the gasket interposedbetween the j tank and the header. "i I Fig. 7 is similarly an enlargeddetail of 60 Fig.- 3 and shows the loose it of the throughbolt in thecored hole of the tank. Fig. 8 is such a sectionfon the line 8--8 v ofFlg. 3 and well shows-the tank bolt hole.

In the construction shown in the draw- 65 ings' the radiator 1 comprisesa plurality yof heat radiating sections 2 in combination with a toptank-3, a bottom tank 4cand ya pairof upright end frame connectors 1.

l' These tanks vand sections are'so formedvwith- 'I0 mutuallyloverlapping flange parts hereinafter described that each end Joint maylbes and is secured by a single loose fittin ten; sion fastening 5, and.the abutting tan and section-end parts orheadersl are each comcallyapertured cellular structurev in 'combif 80 -nation with a pair 'ofterminal parts or headers 7, one ateach end,'with whichthe verticalwater passageways all communicate.

fThe headers 7 are substantially 'alike and are secured permanently and'substantially S5 integrallyv tothe core 6 at their edges 7, asbywelding orvequivalent means. These sections are symmetrically formedand may be used 'either end up.

Each header 7- isform'ed substantiall asf e0 shown in Fig. 5', and is vreferably vmadzi; as l a casting either from` rass or'malleahl'e iron.They may also be stamped` Sang of the core 6.` It is` formed-asaclosed'boxv like member open at 7' onits under side to receive'thecore-6, which is welded to its. downward edgesas at 7.

The' upper rear 100 corner is recessedat 8 to receive a correspondingflange part or leg 9.of the tank 3.' l The upper side' 'of the header isindented transversely at 10 from' front to back to pro-' vide atrough-like notch or aperture for ltl1e ..105 fasteningbolt 5 which fitsloosely therein. A .pair ofv port apertures 11 are provided in theupright wall 12 of recess 8, one `on each side of the depression 10 to-Iregister withcorresponding port apertures 13 1n the inner H0" i in theleg 9,and likewise they fit loosely in the troughs 10 entirely out ofcontact with moisture and consequently freer from the tendency to rust.

= ping of holes is required either in the tanks or in the headers. Thebolts 5 are simply held in tension by the nuts '5f and serveeil'ectually tc maintain a tight joint, which is easily accessible byremoval of said nuts.

Assuming that the radiator is assembled complete, the method of removina section 2 is to remove the corresponding pair of nuts 5 on the frontside at the top and bottom and then pull the section horizontallyforward and 0E. It may be put on b'y a simple reverse method, which,however, must include holding the loosely disposed bolts 5 positively inplace against Abacking out, toward the right as viewed in Figs. 2 and 3,unless the gaskets 14 bind snugly enough about the bolts to hold them in.place independently of other means.

It should be noted that each of the headerI castings at the upper andlower ends of the core sections is ofuniform depthy across the entireWidth of the core, thus giving l uniform distribution for steam andWater through to all of the water passages in each core section.Moreover, it is connected to the core tanks by a single standard boltwhich passes through both the cored hole in the tank and the groove in,the section header. The cored hole for the bolt is sufciently large toallow assembling these radiatorsections evenif there is a smallvariation in the `length of same' or if the castings vary indepth. Also,if in assemblingx the junction boxesor section-headers on t e upper andlower ends of the cores, any header box -is not set at exactly right Nodrilling or tap? angles in either direction, still there` is sufficientclearance in the cored hole for this .bolt because it is a center boltto permit of these variations, instead of a onel on each side.

From a practical economic standpoint in assembling this radiator, thereis a very material reduction of cost because of these features.Furthermore, in removin the section, there are only two lrough bo ts topair of bolts disconnect instead of vfour `machined cap screws. A roughbolt can be readily obtained as compared with specially machined screws,and nthe fluid passageways Vwhich are cored in the back vportion ofthese headers are so placed on either side of the bolt housing as togiveI substantially uniform distribution to each core section, and theseholes are of such form and area as to accommodate some variance inhorizontal axial registry with the holes in the upper and lower tankcastings and still provide sutlicient open area for the maximum volumeof Water or steam necessary.

Instead ozf there being an individual opening connected with the tank,there is, along the back of `each header practically a continuouspassage for taking the water into nd through the openings in the headeroxes.

Although but one specific embodiment of' this invention is herein shownland described, it is to be understood that some f the details of theconstruction shown may be altered or omitted without departing from thespirit of this invention as deined by the following claim.

I claimf f In a radiator, upper and lower tanks rigidly connected oneabove' the other, a plurality of core sections each having upper andlower headers overlapping vertical faces of said tanks, each of'saidupper and lower headers having .a deep notch in its top and bottom endrespectivelyr to accom- -modate bolts for securing such headers. to theadjacent tanks, and bolts in said notches arranged -,to secure each coresection independently of the others.
